Marrying an Australian citizen does not, by itself, make you an Australian. Australian law has no separate citizenship-by-marriage category. Instead, a spouse follows the same route as any other migrant: get a partner visa, become a permanent resident, live in Australia long enough to meet the residence rule, then apply for citizenship by conferral. Start to finish, that usually takes six to eight years.
The Partner Visa Comes First
Everything begins with a partner visa, and it is granted in two stages under a single combined application. If you are already in Australia when you apply, you lodge the temporary Partner visa (subclass 820) together with the permanent Partner visa (subclass 801). If you are outside Australia, you lodge the provisional Partner visa (subclass 309) with the permanent Partner visa (subclass 100).1Department of Home Affairs. Partner Visas (Apply in Australia)
The Department of Home Affairs first decides whether your relationship is genuine and grants the temporary visa. Roughly two years after you lodged the application, the department reassesses the relationship and, if satisfied, grants the permanent visa.2Department of Home Affairs. Partner Visa (Subclass 801) The two-year gap is built into the process on purpose. Only once the permanent visa is granted do you start counting time toward citizenship.
Queue times sit on top of that design. About 90 percent of temporary partner visa applications are processed within 18 months, though the figure moves month to month. Combined with the mandatory two-year reassessment, most people wait three to four years just to reach permanent residency before the citizenship clock even starts.
What the Partner Visa Costs
The partner visa is one of the most expensive visas Australia issues. The base application fee for either the onshore or offshore partner visa is AUD $9,365 for the main applicant.3Department of Home Affairs. Subclass 820 Partner Visa (Temporary) If you previously held a Prospective Marriage visa (subclass 300), the fee drops to around AUD $1,560. Adding family members costs more: AUD $4,685 per additional applicant over 18 and AUD $2,345 per child under 18.
That one fee covers both the temporary and permanent stages. On top of it, most applicants pay for health checks, police certificates, translations, and often a migration agent. A realistic total budget for a straightforward application is AUD $12,000 to $15,000.
The Four-Year Residence Requirement
Once you hold a permanent visa, the countdown to citizenship begins. You must have lived in Australia on a valid visa for four years immediately before you apply, and you must have held a permanent visa or Special Category Visa for at least the final 12 months of that period.4Department of Home Affairs. Become an Australian Citizen (by Conferral)
Being married to an Australian does not shorten this. You follow the same rules as everyone else applying by conferral. Travel overseas is allowed inside strict limits: your total absences during the four-year period cannot exceed 12 months, and you cannot have been outside Australia for more than 90 days in the final 12 months before you apply.4Department of Home Affairs. Become an Australian Citizen (by Conferral) Frequent travellers get caught out by this often. The department publishes a free residence calculator you can use to check your dates before applying.5Department of Home Affairs. Residence Calculator
If the Relationship Ends Before You Get Permanent Residency
Ordinarily, you need to still be in a genuine relationship with your sponsor when the permanent partner visa is decided. Australian immigration law recognizes three exceptions where you may still be granted the permanent visa after the relationship has ended:2Department of Home Affairs. Partner Visa (Subclass 801)
- Family violence by your sponsor during the relationship. The department may require evidence from police, courts, medical professionals, or social workers, and can refer the case to an independent expert.
- A child of the relationship, or a child for whom your sponsor has formal custody or maintenance obligations.
- Death of your sponsor before the permanent visa is decided, provided you can show the relationship would have continued and you have ties to Australia.
If none of these apply and the relationship has genuinely ended, the partner visa application will likely be refused, though a different visa may be available if you have other grounds to remain.
Applying for Citizenship
Most applicants aged 18 to 59 apply on Form 1300t (Application for Australian Citizenship — General Eligibility). Form 1290 is used in specific situations, including where a permanent physical or mental incapacity prevents the applicant from sitting the citizenship test.6Department of Home Affairs. Application for Australian Citizenship Other Situations Form 1290 You submit through the ImmiAccount online portal or by mail.
The standard fee is AUD $575, adjusted each 1 July.7Department of Home Affairs. Citizenship Application Fees A concession fee of AUD $80 applies if you hold a valid Pensioner Concession Card issued by Services Australia or the Department of Veterans’ Affairs. Health Care Cards, Student Cards, and Senior Health Cards do not qualify. Three groups pay nothing: people who served at least 90 days in the Australian Defence Force, stateless persons applying under section 21(8) of the Act, and British or Maltese former child migrants who arrived under the Commonwealth Child Migration Scheme between 1947 and 1967. Fee-exempt applicants must apply on paper rather than online.
You will need your birth certificate, current passport, and marriage certificate. Arrival records are verified digitally or through your international movement records, which the department provides free on request.5Department of Home Affairs. Residence Calculator You also submit an Identity Declaration (Form 1195), signed by someone who has known you for at least a year, is an Australian citizen, is not related to you, and works in one of roughly 40 approved professions listed on the form.8Department of Home Affairs. Identity Declaration
You must be of “good character.” The department may ask for a police certificate from every country where you lived for 12 months or more in the past 10 years while over 17.9Department of Home Affairs. Character Requirements for Visas A criminal record does not automatically disqualify you; the department assesses each case on its merits, looking at the nature and severity of offences.10Department of Home Affairs. Character Requirements for Australian Citizenship False or misleading information is treated differently and can put your permanent residency at risk.
About 90 percent of citizenship-by-conferral applications are processed within 8 to 9 months of lodgement.11Department of Home Affairs. Citizenship Processing Times
The Test, the Interview, and the Ceremony
After the department processes your application, you are invited to an office appointment. Original documents are physically verified, and most applicants sit a standardized citizenship test on Australian values, history, and democratic government. You need an overall score of at least 75 percent and must answer all five Australian values questions correctly.12Department of Home Affairs. Australian Citizenship Practice Test
Some applicants do not sit the test. Those aged 60 or over or 17 or younger at the time of application are exempt, as are people with a permanent incapacity or impairment that prevents them from completing it.13Department of Home Affairs. Learn About the Citizenship Test Exempt applicants attend an interview instead.
Approval does not make you a citizen. You become an Australian citizen when you attend a formal ceremony and recite the Australian Citizenship Pledge. You choose between two versions, one with the words “under God” and one without.14Department of Home Affairs. Australian Citizenship Pledge Ceremonies are organized by local councils, and 90 percent of approved applicants receive an invitation within 6 months. Total time from application to ceremony averages about 14 months.11Department of Home Affairs. Citizenship Processing Times Citizenship takes legal effect the moment you recite the pledge and the presiding officer signs your certificate. From that point you can vote, hold an Australian passport, work in the public service, serve in the armed forces, and re-enter Australia without a visa.
Realistic Timeline From Marriage to Citizenship
Stacked together, the stages look like this:
- Temporary partner visa processing: roughly 12 to 18 months after lodging the combined application.
- Permanent partner visa eligibility: 2 years after lodgement, plus further processing time.
- Citizenship residence requirement: 4 years in Australia on a valid visa, with the final 12 months on a permanent visa.
- Citizenship processing and ceremony: about 14 months from application to pledge.
If nothing goes wrong and you are already living in Australia when the partner visa is lodged, expect roughly six to eight years from that first application to your citizenship certificate. Partner visa delays, extended trips overseas, or character issues push it further. The common mistake is assuming marriage shortens the timeline. It does not. Marriage opens the door to a partner visa; the residence and citizenship rules that follow are the same ones every other permanent resident faces.
Dual Citizenship
Australia has permitted dual citizenship since 4 April 2002. The current Australian Citizenship Act 2007 does not require you to renounce any prior nationality when you become Australian.15Department of Home Affairs. Australian Citizenship Act 1948 Dual Citizenship Whether your home country allows it is a separate question. Some countries revoke original citizenship on acquisition of another; some do not recognize dual nationality at all. Check with your home country’s embassy before you make the pledge.16Smartraveller. Advice for Dual Nationals If you later travel to your country of origin on its passport, its authorities may not recognize you as Australian, which can limit Australia’s ability to assist you.
